Kinematic Link or Element

Definition: Each part of a machine, which moves relative to some other part is known as a kinematic link ( or simply link ) or element. A link may consists several parts, which are rigidly fastened together, so that they don’t move relative to on an other. Types...

Types of Links

In order to transmit motion, the driver and the follower may be connected by the following three types of links. 1. Rigid Link: A rigid link is one which does not undergo any deformation while transmitting motion, strictly speaking rigid links do not exists. However, as the deformation...

What is Structure? (Definition)

Definition: It is an assemblage of a number of resistance bodies (known as member) having no relative motion b/w them and meant for carrying loads having straining action. A railway bridge, a roof trues machine frames etc are the example of structure.

Difference between a Machine and a Structure

The following differences between a machine and a structure are important from the subject (Machine Design) point of view.   1. The parts of machine move relative to one another, whereas the members of a structure do not move relative to one another. 2. A machine transforms the...

Kinematic Pair (Definition)

Definition: The two links or elements of a machine, when in contact with each other are said to form a pair. If the relative motion between them is completely or successfully constrained (i.e. in a definite direction) the pair is known as kinematic pair. source: Thermodynamics by Youns...

Classifications of Machine Design

The machine design may be classified as follows : 1. Adaptive design. In most cases, the designer’s work is concerned with adaptation of existing designs. This type of design needs no special knowledge or skill and can be attempted by designers of ordinary technical training. The designer only...

General Considerations in Machine Design

General Considerations in Machine Design Following are the general considerations in designing a machine component: 1. Type of load and stresses caused by the load. The load, on a machine component, may act in several ways due to which the internal stresses are set up. 2. Motion of...

Electromechanical systems

Electromechanical systems In the design of any complex system, all the relevant design details must be considered to ensure the development of a successful product. In the development of motion systems, problems in the design process are most likely to occur in the actuator or motor-drive system. When...

Machine Tools

Despite advances in technology, the basic stages in manufacturing have not changed over the centuries: material has to be moved, machined, and processed. When considering current advanced manufacturing facilities it should be remembered that they are but the latest step in a continuing process that started during the...

Manufacturing Engineering

Manufacturing is derived from the Latin word manufactus, means made by hand. In modern context it involves making products from raw material by using various processes, by making use of hand tools, machinery or even computers. It is therefore a study of the processes required to make parts...
